A process of phosphorylation for a mercerized cotton kersey fabric was investigated. After wet oxidation, the phosphorus content in each sample was determined by spectrophotometric analysis. The range was 0.179 to 0.950 mmol g^–1. A significant decrease in the tensile strength of samples resulted from an increase of phosphoric acid concentration in the phosphorylating solution. The mercerization has a positive impact on the process of phosphorylation, as the phosphorus content was found to be three times higher in the samples that underwent mercerization. The sorption properties of phosphorylated cotton fabric were studied using the Cu²⁺ sorption process as a reference. The value of the static exchange capacity for the phosphorylated fabric was determined to reach its maximum when the concentration of the H₃PO₄ in the phosphorylating solution was 1.40 M, and was found to be 1.48 ± 0.11 mmol g^–1 with the phosphorus content equal to 0.898 ± 0.090 mmol g^–1. The sorption of Cu²⁺ by a single phosphorus-containing group occurred for samples with phosphorus content not exceeding 0.80 mmol g^–1. The preliminary studies of micro-quantities of ²⁴¹Am, ²³³U, and ²³⁹Pu radionuclide sorption from aqueous solutions with phosphorylated textile demonstrated the high efficiency.

The dynamic light scattering method was successfully applied to determine the molar mass of nitrocellulose. The methodology of nitrocellulose fractionation in acetonic solutions is described in detail; six polymer fractions with monomodal distribution were obtained. It was shown that the unfractionated colloxylin with polymodal molar mass distribution had mass average molecular mass values of 87.3 ± 14.1, 28.3 ± 7.3, and 0.54 ± 0.17 kDa when investigated by the dynamic light scattering method. The viscometric method only provided integral viscosity average molar mass equal to 56.7 ± 5.8 kDa.

—The chemical compounds formed during the dissolution of the products of gas-phase conversion of the Tokem-308 cationite (analog of KU-2x8) in an HNO₃(vapor)–air atmosphere, obtained by vaporization of 12 M HNO₃, in H₂O and 0.045 and 0.5 M NaOH solutions were studied. Ozonation of the alkaline solutions of the products was studied for utilization of the latter. The sequence of procedures including gas-phase treatment in the HNO₃(vapor)–air atmosphere and dissolution in NaOH followed by ozonation makes it possible to obtain alkaline solutions almost without any toxic aromatic impurities, due to which the solutions are suitable for safe disposal.

Currently, developing disinfectant materials is of utmost importance. A significant advantage of our fabric is its reusability. The disinfectants based on a natural polymer of cellulose have been barely investigated. Our work presents a modified cellulose material, and the data obtained for the first time on the chlorine dioxide generation process when treating the material with a sodium chlorite alcohol solution. A method of applying NaClO₂ onto the fabric by impregnating it with a solution sprayed by an aerosol generator is proposed. This kind of fabric is capable of withstanding multiple usages after pre-washing and rinsing. The lowest alcohols—methanol, ethanol and isopropanol—are proposed as optimal solvents. It was shown that the phosphorylated cotton cellulose fabric impregnated with this solution generates chlorine dioxide during the first 25–35 min. Neither humidity nor expedites improve the process of releasing the chlorine dioxide, but high moisture content in the air causes the complete absorption of ClO₂ by microdrops and its removal from the gas environment. A promising technique for removing the excess ClO₂ by the means of UV treatment is proposed: after 15 min of treating ClO₂ in the gas phase, it disappears entirely. These materials could be used as disinfectants in different industries, such as food and industrial manufacturing.
